Configure Autoregistration

Autoregistration Overview

Autoregistration allows Unified Communications Manager to automatically assign directory numbers to new phones when you plug those phones in to your network.

Autoregistration is enabled on secure mode now. This enhancement provides greater security for your system because you can secure your cluster while provisioning new phones. It also simplifies the registration process because you don't have to disable cluster security to register new phones.

If you create a device pool that allows only 911 (emergency) and 0 (operator) calls, you can use that to prevent unauthorized endpoints from connecting to your network when autoregistration is enabled. New endpoints can register to this pool, but their access is limited. Unauthorized access by rogue devices that continuously boot in and attempt to register to your network is prevented. You can move a phone that has auto-registered to a new location and assign it to a different device pool without affecting its directory number.

The system doesn't know whether the new phones that are auto-registering are running SIP or SCCP, so you must specify this when you enable autoregistration. Devices that support both SIP and SCCP (such as Cisco IP Phones 7911, 7940, 7941, 7960, 7961, 7970, and 7971) auto-register with the protocol that is specified in the enterprise parameter called Auto Registration Phone Protocol.

Devices that support only a single protocol will auto-register with that protocol. The Auto Registration Phone Protocol setting is ignored. For example, any Cisco IP Phones that support SCCP only will autoregister with SCCP even if the Auto Registration Phone Protocol parameter is set to SIP.

We recommend that you use autoregistration to add fewer than 100 phones to your network. To add more than 100 phones, use the Bulk Administration Tool (BAT). For more information, see Cisco Unified Communications Manager Bulk Administration Guide at http://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-maintenance-guides-list.html.

Configure Autoregistration Task Flow

Enabling autoregistration carries a security risk. Enable autoregistration only for brief periods while you add new endpoints to the network.

Procedure

  Command or Action Purpose

Step 1

Configure a Partition for Autoregistration

Configure a route partition to use specifically for autoregistration to limit auto-registered phones to internal calls only.

Step 2

Configure a Calling Search Space for Autoregistration

Configure a calling search space to use specifically for autoregistration to limit auto-registered phones to internal calls only.

Step 3

Configure a Device Pool for Autoregistration

Create a device pool that uses the calling search space that is configured for autoregistration.

Step 4

Set the Device Protocol Type for Autoregistration

Use this procedure to set the protocol to SCCP or SIP to match the type of phones you are auto-registering.

Step 5

Enable Autoregistration

Enable autoregistration on the node to use for autoregistration and set the Auto-registration Cisco Unified Communications Manager Group parameter to enable autoregistration for the Cisco Unified Communications Manager group that is to be used for autoregistration.

Step 6

Disable Autoregistration

Disable autoregistration for the node as soon as you are finished registering new devices.

Step 7

Reuse Autoregistration Numbers

Optional. Autoregistration numbers for devices that have been disabled can be reused. When you reset the range of autoregistration directory numbers, you force the system to search again from the starting number. Available directory numbers are reused.

Configure a Partition for Autoregistration

Configure a route partition to use specifically for autoregistration to limit auto-registered phones to internal calls only.

Procedure

Step 1

From Cisco Unified CM Administration, choose Call Routing > Class of Control > Partition.

Step 2

Click Add New to create a new partition.

Step 3

In the Partition Name, Description field, enter a name for the partition that is unique to the route plan.

Partition names can contain alphanumeric characters, as well as spaces, hyphens (-), and underscore characters (_). See the online help for guidelines about partition names.

Step 4

Enter a comma (,) after the partition name and enter a description of the partition on the same line.

The description can contain up to 50 characters in any language, but it cannot include double quotes ("), percentage sign (%), ampersand (&), backslash (\), angle brackets (<>), or square brackets ([ ]).
If you do not enter a description, Cisco Unified Communications Manager automatically enters the partition name in this field.

Step 5

To create multiple partitions, use one line for each partition entry.

Step 6

From the Time Schedule drop-down list, choose a time schedule to associate with this partition.

The time schedule specifies when the partition is available to receive incoming calls. If you choose None, the partition remains active at all times.

Step 7

Select one of the following radio buttons to configure the Time Zone:

  • Originating Device—When you select this radio button, the system compares the time zone of the calling device to the Time Schedule to determine whether the partition is available is available to receive an incoming call.
  • Specific Time Zone—After you select this radio button, choose a time zone from the drop-down list. The system compares the chosen time zone to the Time Schedule to determine whether the partition is available is available to receive an incoming call.

Step 8

Set the Device Protocol Type for Autoregistration

If you have SIP and SCCP devices to auto-register, you must first set the Auto Registration Phone Protocol parameter to SCCP and install all the devices that are running SCCP. Then change the Auto Registration Phone Protocol parameter to SIP and auto-register all the devices that are running SIP.

Before you begin

Configure a Device Pool for Autoregistration

Procedure

Step 1

In Cisco Unified Communications Manager Administration, select System > Enterprise Parameters.

Step 2

In the Enterprise Parameters Configuration window, select either SCCP or SIP in the Auto Registration Phone Protocol drop-down list, then click Save.

What to do next

Enable Autoregistration

Enable Autoregistration

When you enable autoregistration, you must specify a range of directory numbers that get assigned to the new endpoints as they connect to the network. As each new endpoint connects, the next available directory number is assigned. After all the available autoregistration directory numbers are used up, no more endpoints can auto-register.

New endpoints auto-register with the first Unified Communications Manager node in the group that has the Auto-Registration Cisco Unified Communications Manager Group setting enabled. That node then automatically assigns each auto-registered endpoint to a default device pool according to the device type.

Before you begin

Set the Device Protocol Type for Autoregistration

  • Create a device pool, calling search space, and route partition that restricts the access of devices that are auto-registering to allow only internal calls.

  • Ensure that directory numbers are available in the autoregistration range.

  • Ensure that there are enough license points available to register the new phones.

  • Check that the correct phone image names for SIP and SCCP appear on the Device Defaults Configuration window. Although most of the common device configuration files should be available on the TFTP server, make sure that the configuration files for your devices are there.

  • Ensure that the Cisco TFTP server is up and running and that the DHCP option for TFTP specifies the correct server.

Procedure

Step 1

From Cisco Unified Communications Manager Administration, select System > Cisco Unified CM, then click Find in the Find and List Cisco Unified Communications Managers window.

Step 2

Select the Cisco Unified Communications Manager in the cluster to use for autoregistration.

appears.

Step 3

In the Cisco Unified CM Configuration widow, configure the autoregistration parameters for the node in the Auto-registration Information section, then click Save. For more information on the fields and their configuration options, see the system Online Help.

  1. Select the universal device template to use for autoregistration from the drop-down list.

    If no universal device template is created for autoregistration, you can select Default Universal Device Template. Make sure that the selected template specifies the device pool that is to be used for autoregistration from User Management > User/Phone Add > Universal Device Template.

  2. Select the universal line template to use for autoregistration from the drop-down list.

    If no universal line template is created for autoregistration, you can select Default Universal Line Template. Make sure that the selected template specifies the calling search space and the route partition that are to be used for autoregistration from User Management > User/Phone Add > Universal Line Template.

  3. Enter the starting and ending directory numbers in to the Starting Directory Number and Ending Directory Number fields.

    Setting the starting and ending directory numbers to the same value disables autoregistration.

  4. Uncheck Auto-registration Disabled on this Cisco Unified Communications Manager to enable autoregistration for this node.

Always enable or disable autoregistration on only the selected Unified Communications Manager node. If you switch the autoregistration function to another node in the cluster, you must reconfigure the Unified Communications Manager nodes, the Default Unified Communications Manager group, and the default device pools that you used.

Step 4

Select System > Cisco Unified CM Group, then click Find in the Find and List Cisco Unified Communications Manager Groups window.

Step 5

Select the Unified Communications Manager group to enable for autoregistration.

In most cases, the name of this group is Default. You can choose a different Cisco Unified Communications Manager group. The group must have at least one node selected.

Step 6

In the Cisco Unified CM Group Configuration window for that group, select Auto-registration Cisco Unified Communications Manager Group to enable autoregistration for the group, then click Save.

Tip

 

Ensure that the Selected Cisco Unified Communications Managers list contains the node that you configured for autoregistration. Use the arrows to move the node to appear in the list. The Unified Communications Manager nodes get selected in the order in which they are listed. Save your changes.

Step 7

Install the devices that you want to auto-register.

Note
You can proceed to reconfigure the auto-registered phones and assign them to their permanent device pools. The directory number that is assigned to the phone does not change when you change the phone location.

Note
To register phones of a different type, change the device protocol type and install those devices before disabling autoregistration.

Disable Autoregistration

Disable autoregistration for the node as soon as you are finished registering new devices.

Before you begin

Enable Autoregistration

Procedure

Step 1

In Cisco Unified Communications Manager Administration, select System > Cisco Unified CM, then click Find in the Find and List Cisco Unified CM window.

Step 2

Select the Cisco Unified Communications Manager from the list of nodes.

Step 3

In the Cisco Unified CM Configuration widow for the selected node, check the Auto-registration Disabled on this Cisco Unified Communications Manager check box to disable autoregistration for this node, then click Save.

Tip

 

Setting the same value in the Starting Directory Number and Ending Directory Number fields also disables autoregistration.

What to do next

Optional. If you manually changed the directory number of an auto-registered device, or if you delete that device from the database, you can reuse the directory number. For details, see Reuse Autoregistration Numbers.

Reuse Autoregistration Numbers

When you connect a new device to the network, the system assigns the next available autoregistration directory number to that device. If you manually change the directory number of an auto-registered device, or if you delete that device from the database, the autoregistration directory number of that device can be reused.

When a device attempts to auto-register, the system searches the range of autoregistration numbers that you specified and tries to find the next available directory number to assign to the device. It begins the search with the next directory number in sequence after the last one that was assigned. If it reaches the ending directory number in the range, the system continues to search from the starting directory number in the range.

You can reset the range of autoregistration directory numbers and force the system to search from the starting number in the range.

Procedure

Step 1

In Cisco Unified Communications Manager Administration, select System > Cisco Unified Communications Manager

Step 2

Select the Cisco Unified Communications Manager to reset for autoregistration.

Step 3

Write down the current settings in the Starting Directory Number and Ending Directory Number fields.

Step 4

Click Auto-registration Disabled on this Cisco Unified Communications Manager, then click Save.

New phones cannot auto-register while autoregistration is disabled.

Step 5

Set the Starting Directory Number and Ending Directory Number fields to their previous values, then click Save.

Tip

 

You could set the fields to new values.
